Disadvantages of the 1MZ-FE engine
The engine frequently starts an impressive oil burner at high mileage;
Knock sensors are not very reliable and frequently need to be replaced;
Throttle fouling causes variations in engine speed;
engine problems in the event that the VVT-i phase regulator valve fails;
Overheating is a major concern for this power unit.
When there is a lot of frost, drivers sometimes complain that the vehicle won’t start;
Particularly in the manifolds, the motor is susceptible to increased carbon formation.
